NAME
RegGetValueW (ADVAPI32.@)SYNOPSIS
LSTATUS RegGetValueW(
HKEY hKey,
LPCWSTR pszSubKey,
LPCWSTR pszValue,
DWORD dwFlags,
LPDWORD pdwType,
PVOID pvData,
LPDWORD pcbData
)
DESCRIPTION
Retrieves the type and data for a value name associated with a key, optionally expanding its content and restricting its type.
PARAMS
hKey [In] Handle to an open key.pszSubKey [In] Name of the subkey of hKey.
pszValue [In] Name of value under hKey/szSubKey to query.
dwFlags [In] Flags restricting the value type to retrieve.
pdwType [Out] Destination for the values type, may be NULL.
pvData [Out] Destination for the values content, may be NULL.
pcbData [In/Out] Size of pvData, updated with the size in bytes required to retrieve the whole content, including the trailing ' ' for strings.
RETURNS
Success: ERROR_SUCCESS
Failure: nonzero error code from Winerror.h.
NOTES
- Unless RRF_NOEXPAND is specified, REG_EXPAND_SZ values are automatically expanded and pdwType is set to REG_SZ instead.
- Restrictions are applied after expanding, using RRF_RT_REG_EXPAND_SZ without RRF_NOEXPAND is thus not allowed.
